BURGLAR-ALARM.

SPECIFICATION forming part of Letters Patent No. 414,308, dated November 5, 1889.

Application filed July 19, 1889. Serial No. 317,974. (No model.)

To all whom it may concern.-

Be it known that I, ALBERT A. GOUCHER, of Euclid, in the county of Butler and State of Pennsylvania, have invented certain new and useful Improvements in Combined Electric Burglar-Alarms and Indicators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvementin combined electric burglar-alarms and indicators; and it consists in the combination and arrangement of parts which will be more fully described hereinafter, and pointed out in the claims.

The object of my invention is to produce a combined electric burglar-alarm and indicator which is cheap and simple in arrangement, and by my arrangement to produce certain advantages and results hereinafter set forth.

Figure l is a plan View of my invention complete. Fig. 2 is a front View of the indicator. Fig. 3 is an enlarged detached View of the contact-points placed in the windows and doors. Fig. at is an enlarged detached view showing the rods L constructed to operate independent of each other.

I will first describe the mechanical constru 0- tion of my invention and then proceed to describe the circuit and its operation.

The alarm is secured to the top of the indicator-frame, while the indicator mechanism is placed below it.

In the drawings, A indicates a metallic base having the two electroqnagnet supports B C extending at right angles to its surface. These supports 13 O are sufficiently broad to allow the magnets D E to be secured thereto at their lower ends, as shown. Also secured to the base A, and extending therefrom a suitable distance at right angles to its surface, is the metallic L-shaped frame or support F. Pivoted at its inner end upon that end of this support F which is nearest the magnets D is the armature G, which extends across over the cores of the magnets, as shown, and is provided with a clapper at its free end. Se-

cured to but insulated from the L-shaped support F is the projection H, having a setscrew I passing through its outer end and engaging a spring contact J, which is secured to the armature G. Fastened to the inner end of the armature G is a spring K, which is engaged at its outer end by the regulating screw L, that passes through the L-shaped support F. By means of the two regulatingscrews I and L the tension of the armature G is adjusted as may be required to suit the strength of the current passing through the magnets D.

M N are two projections or short arms secured to and insulated from the L-shaped support F. Each of these arms is provided with a contact-screw that engages the free end of the armature O as it vibrates between them. This armature O is pivoted to a suitable projection P, extending outward a suitable distance aud insulated from the base A. A bell Q of any description is secured to a support R, extending from the base A, as shown.

Referring to the construction of my indicator, which consists of a suitable box-like frame made in any desired shape and of any size to suit the number of indicators to be placed therein, S represents the front of the indicator frame or box, which is provided with a suitable number of apertures which form journals for the shafts U of the indicators T.

As here shown, I prefer to make the indicators in the form of boys, and of any desired metal, such as lead, bronze, orany nickelplated metal which will give a finish to the appearance of the indicator. These indicators are secured to the outer ends of the shafts U, so that they will fall to a horizontal position, as shown at numbers 2 and 4: upon the face of the indicator when the shafts are left free to move.

V N indicate metallic supports, which are secured to the back of the indicator at such positions as to support the two pairs of magnets X Y and the armatures A in their proper relation to the indicator-shafts, as will be fully described hereinafter. Thesemetal supports V W are here shown as being secured to the back of the indicator separately; but it will be readily understood that they can be first secured to a suitable base, and that fastened to the back of the indicator, or the base and supports made of one piece, as are the supports 13 C and base A of the alarm. The support W has secured to it the lower ends of the two pairs of magnets X Y,

as shown, which extend upward therefrom within suitable proximity to the upper support V, to which the operating mechanism, hereinafter described, is fastened. As the mechanism of the two magnets X Y for operating the indicators are the same, similarletters of reference will be used for each.

I will here state that one pair of magnets is used in connection with each indicator for operating it.

A represents armatures, which have their upturned ends formed into springs and fastened to the supports V, and extend over the cores-of the two pairs of magnets, as shown.

B indicates two latches having upturned ends similar to the armatures A, and which are also fastened to the support V. The outer ends of these latches B are formed into catches C, with which the outer ends of the levers D, secured to the inner ends of the indicator-shafts II, engage when they are drawn down. As here shown, the mechanism of magnets Y is set, and the head of its boy indicator covers its adjacent number upon the face of the indicator, while the mechanism of the magnets X is released and the boy indicator is horizontal, exposing its adjacent number. Extending downward from the outer vibrating ends of the latches B are arms ha"- ing two lateral projections or stops F, with which the free ends of the armatures A alternately engage. The armatures A are provided with springs E, which are engaged by the regulating-screws G, which pass through the support V. By means of these screws the tension of the armature is regulated according to the strength of the current passing through the magnets. Similar springs are secured to the inner ends of the latches B, which are engaged by regulating-screws H, passing through the support V, which hold the outer ends of the latches in contact with the levers D when drawn. downward. To limit the upward movement of the latches, and thus prevent them from rising too high to allow the lower ends of the levers D to press them down, stops I are provided.

Projecting outward from the back of the indicator are rods J which are provided with,

perforations in their outer ends, through which the upper ends of the vertical set-rods L pass. The lower ends of these rods are fastened to a connecting-bar M, having a downwardly-extending bar N, which passes through a guide 0, and is provided with an operating-button upon its lower end. Surrounding this bar N is a spiral spring which engages the guide 0 and the crossbar l whereby the bar and rods are normally held in an upward position. Connecting the rods L and the levers D are the chains, cords, or wires P.

From the above description it will be seen that when a downward pull is exerted upon the operating-button the rods L are pulled downward, and through the medium of the chains P the levers D also, and the lower ends of said levers being thereby made to engage .t-he latches O, which hold them in this position and the indicators set.

While I here show only two indicator magnets and mechanisms, it will be seen that as many of them may be secured to the support W as desired, and all of the set-rods L secured to a connecting-bar M; or these lower ends of the rods L may separately pass through guides and operate independently one of the other, as shown in Fig. 4:.

In Fig. 3 is shown a spring and contactpoints which I use in connection with the If desired, the indicator may be omitted and my invention used as an alarm between a residence and a store by connecting the wires with the windows and doors, as here shown. When any door or window is then opened, an alarm will be sounded at the residence; or, should the wire or wires be cut or tied, an alarm will be-likewise sounded;

U represents a pin by means of. which the main-line circuit is broken, and V a pin by means of which the local or alarm circuit is I broken.

The course of the circuits and the operation of my invention are as follows: The circuits through the wires will be indicated by numerals. ing an alarm by reason of the window W having been raised. WVhen the window was raised, the main-line circuit, through the local battery 1,wire 2, armature O,arm N, continuing through main wire 2, through doors and windows, to main -line battery 3, through main-line wire 2 to magnets E, through the iron base, as indicated by dotted line, the L- shaped support F, armature G, spring J, screw I, projection H, to other pole of local battery 1. Thus it will be seen that when the outer end of armature O is made to engage the screw in lower arm N- a continuous main circuit is formed through both the main and local batteries; but, as here shown, the main circuit The instrument as here shown is soundthrough the magnet E is broken, thus releasing the armature 0, allowing it to be drawn upward by means of the spring X, whereby it engages the screw in the upper arm M of the L-shaped support and causes a local circuit to be formed through the magnets D, which, by means of the spring J, causes the circuit to be continuously opened and closed and an alarm sounded until the armature O is forced downward, breaking the local and closing the main circuit, or the local circuit be broken independently of the main circuit by removing the pin V. The local circuit is through the battery 1, main-line wire 2, armature 0, arm M, and local-circuit wire 4, magnets D, base A, L-shaped support F, armature G, spring J, screw 1, arm ll, and main-line wire 2, to opposite pole of battery 1. Thus it will be seen that the local circuit passes through the main-line circuit by this construction, needing only the local wire 4 to connect the magnets D and armature O. From this it will also be seen that the local circuit is closed by the opening of the main circuit. A circuit is caused to pass through the indicator-line and indicators by means of the spring S, engaging the contact R when the Window was raised, making a current through the wire 5 to the magnets X, through the magnets and the wire 6, to the main line 2, the main-line battery 3, and on through the main line 2 to the spring S, thus completing the indicator-circuit through the main-line battery. By this construction it will be seen that by the breaking of the main line two separate circuits were formedviz., through the indicator and through the alarmand at the same time using most of the mainline circuit for each. Thus I am enabled to cheapen and simplify an alarm and indicator by this arrangement of parts, wires, and batteries. The magnet Y is connected with the door Z by the wire 7 in the same manner that the magnets X are connected with the window, so that when the door is opened a circuit is passed through the magnets Y by means of the wire '7. A separate wire connects with each door and each pair of indicator-11mgnets, as will be inferred from the above description. In this way, each indicator and indicator-magnet is operated independently of the others. Vhen the indicator-circuit was completed, as above described, the magnets X were magnetized, attracting the armature A, which exerted a downward pull upon the latch B, thus releasing the lever D. By the-releasing of the lever the boy indicator is allowed to drop to a horizontal position by reason of its gravity, exposing its adjacent number upon the face of the indicator, and thus designating the window or door that has been opened.

Having thus described my invention, I claim 1. In a burglar-alarm, the combination, with a window or door and an electric con tact secured thereto which is broken by the opening of the door or window, of set magnets and an armature operated thereby for setting the main circuit, contact-points which are alternately engaged by the free end of the armature, alarm-magnets and an armature operated thereby, a contact-point which is alternately engaged by said armature, and local and main batteries, a wire connecting one pole of the local battery wit-h the set armature, and a wire connecting its oppo site pole with the alarm-armature contact point, a wire connecting one pole of the main battery with the set magnets, and a wire connecting the opposite pole of said battery with the contacts upon the doors and windows and with one of the set armature contact-points, and a local'circuit wire con necting the other set armature-contact and the alarm-magnets, indicator-magnets and wires connecting the said'magnets with a contact upon a window or door and with one pole of the main battery, respectively, where by, when the main-line circuit is broken,two separate circuits are formed, one through the alarm magnets and one through the indicator-magnets, substantially as shown and described.

2. In a burglar-alarm, the combination of a base-plate alarm and set magnets attached thereto at right angles to each other, set armature, an L-shaped support having two contact-points which are alternately engaged by the set armature, an alarnrarmature piv oted to the opposite end of the L-shaped casting, having a spring attached thereto, a contact-point secured to the said support and engaging the said spring, a bell supported upon the base, and the alarm-armature elongated and provided with a clapper, contactpoints secured to the windows and doors, a main and a local battery, one pole of the local battery being electrically connected with the set armature, and its opposite pole electrically connected with the alarm-armature contact, and one pole of the main battery being electrically connected to the set magnets and the other pole electrically connected with the contacts upon the windows and doors, and with one of the set armature contact-points, and a local-circuit wire connecting the other set armature contact with the alarm-magnets, whereby, when a window or door is opened, the current thus formed through the two batteries is broken and a circuit formed through the local battery and the alarm-magnets alone, substantially as specified.
